The measure passed the Legislature last month after failing twice in the past decade.

Starting next school year, illegal immigrants who were brought to the U.S. as children and graduated from an Oregon high school would pay the subsidized college tuition charged to Oregon residents. That's a savings of about $20,000 a year.

Proponents say young people shouldn't be priced out of college because their parents chose to immigrate illegally. Critics say the state shouldn't be subsidizing a college education for people who violated immigration laws.

At least 14 other states have similar laws. Colorado's Legislature approved a tuition bill, and Gov. John Hickenlooper has said he'll sign it.
